Abstract
Systems and methods and augments for supporting an acetabular shell at a hip bone. An example system of modular augments can include first and second augments, each having a body extending from a respective first end portion to a respective second end portion. The first augment second end portion can include a first coupling element and the second augment first end portion can include a second coupling element. Together the first and second coupling elements can form a coupling mechanism to join the first and second augments together. In some examples, the coupling mechanism can include a bulbous tip portion and a recess to receive and retain the bulbous tip portion.

A system of modular augments for supporting an acetabular shell at a hip bone, the system comprising:
- a first augment;
- and
- a second augment,
- wherein each of the first and second augments has a body extending from a first end portion to a second end portion,
- wherein the first augment first end portion has a first coupling element,
- wherein the first augment second end portion has a second coupling element,
- wherein the second augment first end portion has a first coupling element,
- wherein the first augment second coupling element and the second augment first coupling element form a coupling mechanism to join the first augment and the second augment of the system of modular augments together,
- wherein one of the first augment second coupling element and second augment first coupling element comprises an extension portion and a bulbous tip portion, and the other one of the first augment second coupling element and the second augment first coupling element comprises a recess having a first portion to receive the extension portion and a second portion to receive the bulbous tip portion, wherein the first portion is narrower than the bulbous tip portion and inhibits movement of the bulbous tip portion into the first portion.
An acetabular implant system, the system comprising:
- an acetabular shell having a first surface configured to face an acetabulum, and a second surface opposite the first surface, a depression in the second surface, and an opening extending from the first surface to the second surface;
- an acetabular shell support including a body extending from a first end portion to a second end portion, the first end portion having a first surface including a first coupling element positionable adjacent to the acetabular shell;
- and
- an elongate coupling member including an extension portion and a bulbous tip portion, wherein the extension portion is adapted to extend through the opening of the acetabular shell from the first surface to the second surface and to be coupled to the first coupling element, and the bulbous tip portion is adapted to be captured in the depression when the elongate coupling member is coupled to the first coupling element.
An acetabular implant system, the system comprising:
- an acetabular shell having a first surface and a second surface, and an opening extending from the first surface to the second surface;
- an acetabular shell support having a first coupling element;
- and
- an elongate coupling member having an extension portion and a bulbous tip portion, wherein the extension portion is adapted to extend through the opening from the first surface to the second surface, the bulbous tip portion is adapted to be constrained by the acetabular shell, and the extension portion is adapted to be retained by the first coupling element, wherein the bulbous tip portion is three-dimensionally rotatable within the opening to adjust an orientation of the acetabular shell support with respect to the acetabular shell.
